What does a double bend sign indicate?

A double bend sign is used to inform drivers that the road ahead will curve in one direction and then subsequently in the opposite direction. This sign usually consists of two arrows, each indicating a bend in the road. When you see this sign, it signifies that after the first curve, a second curve in the opposite direction will follow soon after.

Understanding that the road curves to the left first is crucial for safe driving, as it allows drivers to adjust their speed and positioning accordingly. This advance warning helps prevent accidents that could occur if a driver is taken by surprise by sudden changes in road direction.
